"'MUDQGRIP Fon AUTOMOBILES. j Y

T all whom 'z'tmay concern 'v Be it knownl thatII',=JAMEs M. FRASER, a lcitizen of Canada residing atfEmpress, in the Province of lberta and Dominion of Canada,' have invented new and usefull Improvements .in Mud-Grips for Automobiles,

Y. of which the following 'is a specification.

vThis invention yrelates to vniud grips for automobilesand other ymotor driven vehicles, the object of the invention (being to produce 'aneflective and economical attachment apj licableto the-wheel of an automobilel and;

' esi edto obtain a lirm hold and grip on a -mu dy .section of-a road to enable the machine to be driven therefrom to more solid ound.'v i With theabove and other` objects in View,

`fthe invention consists ,in the novel construction,- combinationzand arrangement ofA parts,

as will hereinafter be more` fully described, illustrated and claimed. I

- In the accompanying drawings z-Figure 4 1 is a. side elevation of a portion of the driv- 1wheel 4of al motor propelled machine showin the mudgrip of this invention apf through the same 'on an enlarged scale.

Fig. `f3 is a perspective view of the mudv grip detached. Fig. `41is aperspectimaa- View similar to Fi 3 showing the use of chains in' Vstead'ofit e links illustrated inlg.. 3.'

' The mud grip contemplated i'n this invention is composedof a longitudinal series of gripping elements' v connected together byl links so as to adapt the mud gripv as a whole i to be placed longitudinally around the tire of, :ajwheel the?y manner illustrated in ach of the gripping elements 1s composed of metal and comprises a .body portlon v1 i adapted .to rest against theftread portion of parallel links 3 as `best illustrated in Fig. 3,

the saidlinks being shown as consisting of short lengths of rods 4headed as shownat 4:

and passed through. holes in the gripping sections, thereby permitting the mud grip.)-

asa Whole vto be placed around the tire to conform to the rcircu'mferenceand curvfaf ture4 thereof. .f" 1

Each? ofthe grippingfelenlents isprovided--- on the'inner side thereofwith a substantially .U-shaped stirrup' consisting of a strap of iron bent into shape and rivetedor otherwise4 fastened as shown at 6to the body portion of its respective lgripping element.' Thenl properrelation.tothetire.` i

' At opposite sides of the center-ofeaclny stirrup 5, the body portion l of each grip' f ping` element is' provided with,` holes' 6 land felly and securingy the ends thereoflto-` gether between the spokes.

When themud grip hereinabove ldescribed 1s placed uponlone of the'drivinguwheels of y* the machine, and powertransmitted to said wheel from the engine, thev flanges or gripplng portions 2 obtain a firm positive hold or'grip on any soft surface such as mudl A 7o through-which is passed a flexible strap .7 1
